Flesh-eating zombies aren't the only worry thing to be worried about in the second season of "The Walking Dead."

Sarah Wayne Callies, who plays one of the survivors in the AMC zombie apocalypse saga, teased during a Friday panel at Comic-Con that "the most dangerous things out there are the monsters inside."

Robert Kirkman, executive producer and creator of "The Walking Dead" graphic novel series, announced that the 13-episode second season will premiere Oct. 16.

Frank Darabont, the show's creator and executive producer, promised fans that the second season picks up five seconds after the first season finale, when the survivors drove away from the destroyed Centers for Disease Control and Prevention in Atlanta.

A trailer featuring the survivors running from zombies amid a traffic jam was also shown.
